This is a list of possibly hazardous near-Earth objects with Torino scale rankings that are non-zero or that were, at one time, non-zero.
Potential impacts with high ratings.
In March 2002, became the first asteroid with a temporarily positive rating on the Torino Scale, with about a 1 in 9,300 chance of an impact in 2049. Additional observations reduced the estimated risk to zero, and the asteroid was removed from the Sentry Risk Table in April 2002.
Most potential impacts listed on NASA's Sentry List Table or ESA's Risk List have a Torino scale rating of 0, a few each year reach a rating of 1. , only three objects ever received a rating above 1.
On December 24, 2004, asteroid 99942 Apophis was assigned a 4 on the Torino scale, the highest rating given to date, for an impact in April 2029. As observations were collected over the next three days, the calculated chance of impact first increased to as high as 2.7%, then fell back to zero. The risk of impact during later close approaches was eliminated and Apophis was removed from the Sentry Risk Table in February 2021.
In February 2006, , having a diameter around 300 metres, was assigned a Torino Scale rating of 2 due to a close encounter predicted for May 4, 2102. After additional observations allowed increasingly precise predictions, the Torino rating was lowered first to 1 in May 2006, then to 0 in October 2006, and the asteroid was removed from the Sentry Risk Table entirely in February 2008.
In late January 2025, asteroid was assigned a Torino scale rating of 3, and had a chance of impact as high as 3.1% on December 22, 2032. Astronomers responded by scheduling more observations (including the James Webb Space Telescope) as the object receded and got dimmer, to determine its orbit with more precision and thus improve the impact risk prediction. Had been confirmed to be on collision course with Earth, its Torino scale value would have been upgraded to 8. The DART mission has proven the capability of redirecting small asteroids, and currently active launch vehicles are sufficient to redirect if it had been determined necessary during 2028. However, it was downgraded to a Torino Scale rating of 0 on February 23, 2025.
List of potential impacts with non-zero peak ratings.
Below is a comprehensive list of asteroids with potential impacts on Earth over the next 100 years that had been assigned peak cumulative Torino scale ratings above 0 on NASA's Sentry Risk Table.
Downgraded to zero.
This is a partial list of near-Earth asteroids that have been listed with a Torino scale rating of 1+ and been lowered to 0 or been removed from the Sentry Risk Table altogether. Most objects that reach a Torino scale of 1 have a short observation arc of less than 2 weeks and are quickly removed as the observation arc gets longer and more accurate.
